Start by placing the boneless, skinless chicken breasts at the bottom of your crockpot. These will become incredibly tender as they cook.
Sprinkle the garlic powder, salt, cumin, and chili powder evenly over the chicken. This will infuse wonderful flavors into the meat as it cooks.
Next, pour the frozen sweet corn over the seasoned chicken. No need to thaw it; the crockpot will handle that!
In a separate bowl, combine the sour cream, mayonnaise, and cream cheese. Stir until well blended, creating a smooth mixture.
Pour the creamy mixture over the corn and chicken in the crockpot. Gently stir to combine all ingredients, ensuring the chicken is well coated.
Cover and cook on low for 6-8 hours or on high for 3-4 hours. Your kitchen will smell divine!
Once cooked, shred the chicken using two forks and stir everything together. Serve warm, garnished with chopped cilantro and crumbled queso fresco.
